In a process for the separation of solid particles from an aqueous liquid by electroflotation, at least one of the electrodes used is formed from carbon fibres. An apparatus for carrying out the separation comprises a tank containing an anode and a cathode, at least one of these electrodes being formed from carbon fibres. The tank has an inlet for the aqueous liquid containing solid particles and an outlet for clarified liquid and means for removing solid particles which have been carried upwardly in the tank. The electrodes preferably comprise carbon fibres set in an electrically-insulating matrix and having exposed ends of carbon fibres substantially throughout the length of the electrode. |
